Will a air pump for air shocks a 93 olds van fit for a 2001 buick

The short answer is no.
Some of the parts may fit, but most are different part numbers.
The engine codes are different, and you would need to look the part numbers up online and compare.
I know the ball joints are different, so the rest of the suspension and brake parts are probably different too.
The coils and fuel pump might interchange.

Remove the drive belt.
Disconnect the two hoses (one pressure, one return) from the pump... catching the contents of the pump's reservoir with a pan under the vehicle. Crowfoot six-point fitting wrenches are strongly suggested for removing the hoses.
Unbolt the pump from its bracket.
Remove the pump.
Replace with a new or rebuilt or salvage pump, reversing these steps.
After refilling the reservoir to the full mark, start the engine and turn the steering wheel fully against both right and left stops several times to bleed air out of the system. Top off the reservoir to the full mark again.

Hello,

Assuming you did replace with the same type of air-shock, it may seem simple, however ensure the hoses are reconnected and air tight. Spray soapy water on the air lines to check for leaks (you'll need to adjust the load to ensure pump function).
Speaking of pump function; check your pump by turning the key to ON. Wait 30 seconds and you should hear the air pump running under the right rear of the car (under the trunk next to the subframe).
If you can not hear the pump running, then check all fuses. If fuses are good and pump does not run, then it may be time for a replacement pump.

I hope this helps.

You don't. They are automatic, unless someone has replaced them with aftermarket cheap ones. If thats the case, follow the air lines and see if there is a valve to pump them up.

Yes there air shock's, NAPA auto parts stock them, the part number is MA822, they cost about $82.00 for the pair, same part we install here at my repair shop, hope this was very helpful.

you have air shocks on the rear of car and the pump is what fills the shocks with air

Do not try add air.. The air ride has a pump it pumps up to need psi Adding psi can blow your shocks

Yes you can but you need to buy an airline kit . It comes with most manual air shock like for the old buicks etc. IT have a thin plastic air lines with nipplesand "O" ring seals that can be connect to your air shocks. There is also a T- fitting that is include that has an air chuck valve that can be manually inflated. Good luck and thanks for using FIX YA
